Montane Syke Jacket
Here's what other sites are saying:
The Montane Syke Jacket is a trail running softshell with a trick up its sleeves. Designed for use in cooler running conditions either high in the mountains or on low trails during chillier months. Zip the sleeves off, stow them in the rear pocket - and it becomes a simple vest that will provide core body protection as you warm up, or as the sun rises.
